Explosion sink is a flammable gas to prevent coal dust explosion propagation of brittle plastic water containers inverted trapezoidal groove. Primarily for the prevention of dust explosions expand control dust explosion hazards, ensure that the upper and lower exports of coal mining in the region and the first half of coal and rock, excavation face, there is enough water to prevent gas and coal dust explosion expanded, isolated coal Fried spread. The main venue for flameproof sink studio set: a, main mine roadway transportation wings wellbore connectivity and return air roadway; b, adjacent focus back to the wind tunnel roadway transportation between the two mining areas; c, adjacent to the seam Shimen between transport and return air Shimen flame retardant, antistatic, carrying capacity, and no leakage, easy functionality of the installation, flameproof water bag, a coal mine explosion sinks effectively prevent combustible gas and coal dust explosion propagation of reliable products, complete specifications. Product Description: Mine Explosion bag is used to install a container coal mine, water bag shed by installing the technical requirements can be effectively isolated from the composition of gas and coal dust explosion propagation; bag of material produced a flame retardant, anti-static and other safety features. Main Specifications: Volume: 20,30,40,50,60L, 80L retardant properties: meet the standard requirements MT113-1995 surface resistance: ≤3 × 108Ω mist form the best time: <150ms Best mist Duration:> 160ms Best mist column length:> 5m Best mist diffusion column width:> 3.5m optimal spray diffusion column height: 3m
